SHIP-FENDER.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed January 29, 1918. Serial N o. 214,405.

To all whom t may concern:

Be it known that I, THEODORE PowLiN, a subject of the Emperor o-f Austria, resident of W. Maitenburg, Lowville, county of Lewis, and State of New York, have invented certain new and useful Impro-vements in Ship-Fenders, of which the following is a specification.

This invention relates to improvements in ship-fenders, and particularly to types adapted to be disposed so as to completely encircle the hull of a vessel.

The principal object of the invention .is to provide a fender which, when coming in contact with a rigid or stationary object, will permit the ship to glide alongside without injury to itself.

Another object is to provide a fender which is held extended from the hull of the ship at all times.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and sho-wn in the accompanying drawing forming a material part of this disclosure and in which Figure 1 is a side elevational view showing a conventional form of ship and indicating the application of the invention..

Fig. 2 is a fragmental top plan view of the same.

Fig. 3 is a fragmental transverse sectional view taken on line 3-3 of Fig. 2.

Fig. A is an enlarged fragmental side elevational view showing the fender elements, and

F ig. 5 is a transverse sectional view taken on line 5 5 of Fig. 4L.

Secured to the hull 10, of the ship at spaced intervals, are a plurality of rigid brackets 11, similar brackets 12, being immediately below, and rigidly engaged in the outstanding elements of these brackets, are beams, respectively 15 and 16, connected alt their points of intersection 17. The outer ends of the beams carry other brackets 19 and 20, respectively at the top and bottom, with which are engaged shafts 21 and 22,

the same extending so as to encircle the entire hull of the ship, the upper shafts 21,

being above the normal water line, and the lower shafts 22, arranged parallel therewith, are positioned substantially on a level with the keel of the ship.

Secured upon the shafts are hubs 25 and 26, from which extend arms 27 and 28, :formed with washer-like ring-elements 30, having arms 31, engaged by rivets 32, with disks 33, having projections receivable with corresponding countersunk openings formed in the rear of the rings 30, and also having at their center, seats 34, receptive of spheres 35, which extend outwardly slightly beyond the face of the rings 30, the whole forming in eect an infinite number of thrust bearings adapted to make Contact with a fixed or stationary object, the spheres or balls rotating in their seats in a well known manner.

Thus, should the ship come in contact with another ship, a rock, a dock or projectile, it will be received in such manner as not to damage'the hull of the ship, which will be caused to sheer away or be fended ofl'l without damage.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:-

In a ships fender of the character described, the combination of upper and lower bars encircling the entire hull of a ship with huJbs secured upon said bars, arm extensions on said hubs, washer-like rings or ring elements formed with each of said arms, disks adapted to be secured by rivets to said elements, said rings having countersunk openings in the rear part thereof, projections on said disks receivable in the openings of said rings, central seats on said rings, and balls in said seats projecting outwardly slightly beyond the face of said rings, and adapted to rotate on their seats.

In testimony whereof I have aflixed my signature.

THEODORE POWLIN.
